For a capable DIY investor asking do I need a financial advisor, Ritholtz Wealth Management suggests testing the retirement cash-flow handoff, not surrendering a spreadsheet because markets feel noisy.
An $850K portfolio using a 4% planning guideline produces $34K a year, so it does not by itself cover a $5K monthly spending gap. Spreadsheet skill is useful, but it cannot turn an annual shortfall into a retirement paycheck.
One reader with dependable pension income, uncomplicated accounts, and a shared withdrawal plan may reasonably keep managing alone. Another may hold the same funds but face uneven consulting income, concentrated employer shares, or a spouse who has never run the spreadsheet. Ritholtz Wealth Management wrote this for engineers and analytically minded do-it-yourself investors who want to test that difference before paychecks stop.

DIY only, a plan review, or ongoing Ritholtz Wealth Management advice
Three choices can fit a capable self-manager: DIY only, a bounded plan review, or ongoing advice. DIY fits when both people can run a stable withdrawal plan; a focused review fits one retirement decision; ongoing help earns consideration when withdrawals, tax choices, and backup management recur. The IRS limit for 2026 is $24,500 for 401(k) employee deferrals, with an $8,000 age-50 catch-up, while total employee-plus-employer defined-contribution additions can reach $72,000. Higher ceilings do not prove you need an advisor, but a savings worksheet built on old limits can give a false answer.
What changes the answer for a self-manager?
A self-manager's answer shifts once the spreadsheet stops being a shared operating manual. Concentrated employer shares, a retirement date within several years, uneven consulting income, or one spouse unable to run the numbers each justify a review. These are cash-flow risks: a missed withdrawal sequence can force sales after a market drop.
Usually the spreadsheet keeper raises the subject. At home, ask the other person to explain how bills would be paid if the keeper were ill or unavailable. A brother who calls $850K “plenty” without testing a $5K monthly gap misses a $26K annual shortfall under a 4% guideline; put the balance, monthly gap, and annual draw on one page.
Can Patrice cover a $5K monthly gap?
Patrice cannot treat $850K as enough for a $5K monthly gap under a 4% planning guideline, because the annual draw is $34K against $60K of spending. She needs to test income, spending, and the account that supplies each monthly transfer before she can decide whether DIY control is still practical. A planning percentage is a starting input, not a lifetime guarantee.
For illustration, hypothetical Patrice, age 52, opens the household spreadsheet while Teresa is away on consulting work. Patrice is a data scientist; Teresa, age 54, is a mechanical engineer turned consultant with uneven income and a SEP-IRA. They have about $850K invested and hope to retire at age 58, after pricing health insurance before Medicare. Patrice enters a planned $5K a month portfolio-supported household gap: $5K × 12 = $60K a year. Then she applies the 4% planning guideline: $850K × 4% = $34K a year. Finally, $60K − $34K = $26K.
That $26K does not prove their retirement fails. Consultant income, later spending changes, and other nonportfolio income may alter it. It does show why Patrice must separate SEP-IRA saving, consulting income, and recurring spending before deciding if a limited review or continuing help earns its place. Use the site calculator to rerun the same math with your own balance and spending gap.
Put the annual gap ahead of the portfolio balance
Run the handoff before retirement
Use DIY only when both people can reproduce the annual spending gap, account-withdrawal order, and backup plan without the person who maintains the spreadsheet.
| Test | $500K balance | $850K balance | $1.5M balance |
|---|---|---|---|
| 4% annual draw | $20K | $34K | $60K |
| Monthly equivalent | $1,667 | $2,833 | $5K |
| Gap after $60K spending | $40K | $26K | $0 |
| Share of $60K spending | 33% | 57% | 100% |
| $5K gap covered? | No | No | Yes |
- 1. Spending total: Add a year of bank and card transactions, then remove one-time purchases.
- 2. Reliable income: Subtract income that does not rely on selling investments.
- 3. Proposed draw: Convert the remaining annual gap into a monthly transfer amount.
- 4. Backup test: Have the other spouse repeat the calculation without coaching.
Paperwork that tests the spreadsheet
The spreadsheet needs evidence, because remembered spending is usually kinder than actual spending. Gather statements from every custodian, a year of checking and card transactions, pay records, consulting-income records, SEP-IRA paperwork, and the latest federal return from your preparer or tax software. Patrice and Teresa should also mark which cash flows stop at retirement and which costs begin then, including health coverage before Medicare.
The IRS Form 1040 and Schedule 1 show reported income that may not appear in a bank-feed category. IRS Form 5498 can help confirm SEP-IRA contributions and year-end values; it often arrives after the tax filing season, so look for it before assuming it is missing. If taxable investments were sold, Form 1099-B and IRS Form 8949 help test whether the spreadsheet has ignored capital-gains tax. Paperwork is dull. So is finding a tax bill after the withdrawal is already spent.
Ritholtz Wealth Management looks at the cash need and the records behind it before any fund change comes up. Any investment can fall below what you put in, so a withdrawal plan needs room for falling markets, health costs, and changes in retirement rules.

Questions to ask before hiring a do I need a financial advisor
Can I keep managing my index funds and pay for only one retirement-plan review?
Yes. A limited retirement-plan review can focus on the spending gap, withdrawal sequence, tax assumptions, and backup process while you continue selecting and holding your own index funds. Ritholtz Wealth Management can discuss the scope during a first conversation. A review is most useful when a retirement date or major account decision is close.
My spouse has never used our spreadsheet; does that change the choice?
It can. If one spouse cannot locate accounts, identify recurring bills, or reproduce the planned monthly withdrawal, the household has a continuity problem. Write down account locations, the payment schedule, and the person to contact. A bounded review may be enough if the rest of the retirement plan is straightforward.
What happens if one of us gets sick soon after we stop working?
Bills still arrive, investments may still need to be sold for cash, and tax paperwork still has due dates. Keep a written list of accounts, recurring payments, insurance contacts, and the intended withdrawal order where the other spouse can find it. A backup manager matters more than a clever spreadsheet.
Does an $850K portfolio make ongoing advice worth considering?
An $850K balance alone does not answer that question. Under a 4% planning guideline, it produces $34K a year before considering taxes or market changes. Ongoing advice may deserve consideration if that draw supports recurring bills, if the money sits in a mix of taxable, pre-tax, and Roth accounts, or if no other household member can maintain the system.
Could newer retirement-plan contribution limits make our old savings worksheet inaccurate?
Yes. The IRS limit for 2026 is $24,500 for employee 401(k), 403(b), governmental 457, and TSP deferrals, with an $8,000 catch-up at age 50 or older. Compare each worksheet assumption with the current IRS limits, especially when consulting income or employer contributions affect projected savings.
Ritholtz Wealth Management checks the cash-flow handoff
Ritholtz Wealth Management would first reconstruct the planned monthly withdrawal, identify which account is meant to supply it, and test whether a market decline changes the order. The first conversation can cover the work and its fee, and agreed terms are recorded in writing before work begins. Keep DIY control if the cash-flow test is repeatable and shared, seek a bounded review for a specific retirement decision, or consider ongoing help when someone else must maintain the withdrawal system.
A portfolio balance is not a retirement paycheck until it survives the monthly-gap test.
